“It’s flat & motionless Folks! From the Pilot’s basic study guide; please read 1.1.2 & let that sink in! Every Pilot was taught this, but some still don’t get it, (I didn’t at first) & some just stay asleep & yes it does say ‘assumed’ but when does the theory become a spinning reality? Where is the next part B manual to apply Coriolis & curvature nonsense to any flight? Never…because it is a flat & stationary Earth we live & fly on. All flight planning & aerial navigation is based always on a flat motionless plane! Curvature or spin is never accounted for EVER 😱☯️😴”
An Aircraft Model for the AIAA Controls Design Challenge
NASA – 1991 – page 11:
“The nonlinear equations of motion used in this model are general six-degree-of-freedom equations representing the flight dynamics of a rigid aircraft flying in a stationary atmosphere over a flat non-rotating earth” https://www.nasa.gov/centers/dryden/pdf/88248main_H-1777.pdf
Investigation of Aircraft Landing in Variable Wind Fields
NASA 1973 – page14 pdf or 6 on actual report:
“For aircraft problems, the state and measurement models together represent the kinematics of a rigid body for describing motion over a flat, nonrotating Earth…”
